Message

At Sii Poland, I build web and mobile applications with React, TypeScript and Next.js for clients in healthcare, banking and automotive. I implement views, forms and components from Figma designs, following responsive web design and SPA standards.

I integrate front ends with REST APIs and work closely with back-end teams. I also develop and customize a reusable component library in Storybook, with strict TypeScript typing and code reviews supporting consistency.

I write testable code and cover components with Cypress and Vitest. My work has included proof-of-concept solutions and expert consultations for clients, including in healthcare.

Before moving into front-end development, I worked in IT support at Sii Poland and provided technical and business support to Ardent Global users at Euvic. I bring experience with Scrum, Git workflows and technical documentation, and I hold the ISTQB Certified Tester – Foundation Level certificate.
